Method for manufacturing a timepiece hand with a circular cross-section

A method for manufacturing a single-piece timepiece hand by laser light, comprising:

• a first step of obtaining a single-piece part made from predefined material, the part extending along a longitudinal axis;
• a second step of rotating said single-piece part:
• a third step of emitting a first modulation of said laser light;
• a fourth step of exposing a first portion of said single-piece part to said first modulation of said laser light so as to form least a first volume with a circular cross-section, with a length L1 and with a mean diameter D1, the ratio
• L
• 1
• D
• 1
• being less than or equal to 20;
• a fifth step of emitting a second modulation of said laser light;
• and
• a sixth step of exposing a second portion of said single-piece part to said second modulation of said laser light so as to form least a second volume with a circular cross-section, with a length L2 and with a mean diameter D2, the ratio
• L
• 2
• D
• 2
• being less than or equal to 20.
